Re: 70d focus issue - admins answers please.

I have the same issue. It's odd, I've had the 70d since November-ish. I used to be a '2nd shooter' at weddings w/ just my olf Nikon d5100 & a 50mm 1.8 for portraits, and the kit lens for wides. Total N00b. .I started getting a grasp of things, and my wedding partner decided to double-book a bunch fo weddings. Since he was a Canon user, and I was looking for an upgrade to the 5100, I switched to canon & bought a 70D. Since then he's complained about focus issues, blaming me, and since i'm newer to this gig, took it to heart and assumed it was me. I have a steady hand, and believe to not be any kind of user error - I know how to shoot.

Today I stumbled across a video (from the canon forums link) showing two photographers describing their issue w/ live view vs viewfinder view, and focusins on the center focal point for lenses 1.4-4.0... this sounds a LOT like my issue and am praying I can find an answer to this without having to call canon and RMA it.

Of course, it couldn't possibly be you. Anymore than it could possibly be a user error for any of the 50 or so users that have taken to the internet, demanding their pound of meat.

There is no question that the 70D uses different focus technologies depending on whether you're using the viewfinder or live-view. Live-view is more sensitive in low contrast scenarios. But this is true of my 5D2.

You wouldn't start shooting as a 2nd with a camera which you haven't fully mastered on someone's wedding day, would you? Because, the timing you report suggests that you did just that.
